Type.IsNestedFamily 属性

获取一个值，通过该值指示 Type 是否是嵌套的并且只在它自己的家族内可见。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public ReadOnly Property IsNestedFamily As Boolean
用法
Dim instance As Type
Dim value As Boolean

value = instance.IsNestedFamily

public bool IsNestedFamily { get; }

public:
virtual property bool IsNestedFamily {
    bool get () sealed;
}

/** @property */
public final boolean get_IsNestedFamily ()

public final function get IsNestedFamily () : boolean

属性值

如果 Type 是嵌套的并且仅在它自己的家族中可见，则为 true；否则为 false。

备注

如果当前 Type 表示泛型类型的类型形参，则此属性 (Property) 始终返回 false。

TypeAttributes.VisibilityMask 选择可见性属性。

Type 对象的家族被定义为具有完全相同的 Type 及其子类型的所有对象。
